Paragone is a product put out by RenewLife, they also have lots of other intestinal ailment curing products. The cheapest place i've found it has been www.houseofnutrition.com for $20 a box, you need two boxes if you're over 150 lbs though. My mother and sister were recently in Malaysia and i'm certain that the things they've been having trouble with is something they got over there. Body twitches, constipation, crawling sensations...ugh, after i told my mom what i was doing and what all i've passed so far she decided to do the program as well. I wish more people were aware of this, if i have critters i'm sure most everyone else does as well.
